  40Cr steel  is a kind of Chinese GB standard alloy steel for engineering and machinery purpose, and one of the most widely used steel grades. For 40Cr material hardness, specifications and equivalent, please see the table below. After quenching and tempering treatment, 40Cr steel has good comprehensive mechanical properties, low temperature impact toughness, low notch sensitivity, good hardenability, and high fatigue strength in cold oil. When water cooling, the complicated shape of the parts is prone to cracks, the cold bending plasticity is medium, and the cutting workability after normalizing is good, but the weldability is poor, should be preheated before welding, and is generally used in the state of quenching and tempering. DATASHEET & SPECIFICATION The tables below list 40Cr alloy steel datasheet and specification including chemical composition, properties and heat treatment, etc. 40CR STEEL CHEMICAL COMPOSITION   Chemical Composition (%) Grade C % Si Mn Cr 40Cr 0.37 – 0.4

The ST 52 belongs to a standard structural steel grade. A  St 52 Steel Plate   is designed with a superior chemical composition of carbon, silicon, manganese, phosphorous, and sulfur. The content embedded in these plates gives them enhanced resistance to corrosive and oxidative media. The St52 Plate is designed for thickness above 6mm and more. These plates have enhanced resistance to pitting and crevice corrosion. They provide good stability and support to different applications. St52-3 Plate is a low manganese carbon grade that doesn’tputs pressure on subsequent modules. These robust plates can be easily welded in place following standard procedures. The versatile St52 3 Steel showcase slightly lower strength and tolerance compared to an St52 plate. These lightweight components comply with different national and international standards. The St52 Steel Sheetis produced in thicknesses below 6mm and above 0.5mm. These sheets don’t provide stability and add an aesthetical appeal to diffe
